    The DVD-R DVD+R difference can easily be summarized by the following:

    The DVD-R/RW standard was developed by Pioneer, and is used primarily by Apple and Pioneer. These “minus“ discs can only be written to in one layer on the discs surface. In addition, this format is supported by the DVD forum, but is in no way an industry standard. DVD-R/RW discs are cheaper than the “plus” format.

    The DVD+R/RW format is supported by Philips, Dell, Sony, HP, and Microsoft. These discs can be written to in multiple layers, giving them slightly better and more disc storage than the “minus“ format. Because of this additional capacity, they are slightly more expensive than “minus“ discs.

    A couple final things to clear up is the difference between DVD-ROM and DVD+RW, or the other DVD formats I mentioned above. The DVD-ROM drive can only read DVDs, while the other DVD drives can read and write data to DVDs.

    And naturally the DVD+RW CD+RW difference can be explained by the “DVD” or “CD” prefix. DVDs, on average, can store up to 4.7 GB of data, while a CD can only store about 700 MB of data, or about 15% of a DVD’s capacity. While CDs are slightly cheaper, in my opinion, the benefits of DVDs are much greater.

    So now that you’ve learned about the difference between DVD-R, DVD+R, DVD-RW, DVD+RW, and even DVD-ROM, which one is right for you? The easiest way to determine which is more beneficial is to watch the industry trends. A few years ago all pre-built computers were shipping with DVD-ROM drives. Today, most PCs have a burnable DVD drive.

    I feel that the benefits of having a burnable DVD drive far outweigh any additional costs. They store much more data, and they are ideal for storing your home movies to watch on your DVD player.

    My advice is to look at DVD burners that support all of the major formats I’ve mentioned above, DVD-R, DVD+R, DVD-RW, and DVD+RW. While a DVD drive that supports all of these formats may be slightly more expensive, it will allow you to use any type of DVD disc to burn to, and you’ll be protected from any industry shifts to one format or the other.

    What he typed but in a nutshell the main functional differences between DVD-R and DVD+R are:

    1) the DVD recorder's built-in defects management,

    2) the way the recorders format and rewrite DVDs,

    3) the price.
